hm - no luck with 4.0-rc6 on peach-pi yet
<
Wizzup>
oh -- forgot initramfs... that may be the cause
<
Wizzup>
hm - no dice, doesn't boot to anything meaningful
<
sjoerd>
No output over serial?
<
Wizzup>
(I -still- didn't set up a serial)
<
sjoerd>
that makes this stuff so much harder for now
<
Wizzup>
and I'm travelling, with only this laptop, so I'm a bit worried that I'll break it now if I go to the local hackerspace
<
amitk>
Wizzup: try this branch
<
sjoerd>
Ah the rc6 failrus are actually know
<
sjoerd>
that's kernelci misleading me because my boards serial server broke
<
Wizzup>
ah... the IOMMU is also set to =y
<
Wizzup>
CONFIG_DRM_EXYNOS_IOMMU that is
<
Wizzup>
amitk: ok, I will try that if I cannot 4.0-rc6 without IOMMU to work
<
Wizzup>
cannot get*
<
javier__>
Wizzup: yes, exynos iommu has to be disabled on 4.0-rc6
<
javier__>
Wizzup: if you still have issues let me know and I can try booting a 4.0-rc6 on my peach that has serial
<
Wizzup>
javier__: cool, I'm on my way of updating/rewriting some wiki pages once I can get it to work
<
Wizzup>
javier__: ack
<
javier__>
Wizzup: great, I should had done that if only to avoid repeating the same things over and over here :)
<
Wizzup>
I just want to offer a binary working u-boot + kernel version and config for each device as starting point

javier__: hm, no luck
<
Wizzup>
I'll paste my config...
<
javier__>
Wizzup: you are testing with exynos_defconfig right?
<
Wizzup>
exynos_defconfig + disabled IOMMU + enabled some crypto functions + initramfs loaded
<
javier__>
Wizzup: ok, I'll give a try to your config later today
<
Wizzup>
I disabled CONFIG_EXYNOS_IOMMU; should CONFIG_IOMMU_SUPPORT also be disabled?
<
javier__>
Wizzup: no, exynos_iommu should be enough
<
Wizzup>
(disabled)

Wizzup: v4.0-rc6 + exynos_iommu disabled but just well on my peach
<
javier__>
*works just well
<
javier__>
it booted correctly and I've display working here
<
javier__>
Wizzup: let me push my branch that I used for test
<
Wizzup>
I did this after compiling the kernel
<
Wizzup>
cat arch/arm/boot/zImage arch/arm/boot/dts/exynos*peach-pi*.dtb > zImage.dtb-peach-pi
<
Wizzup>
mkimage -A arm -O linux -T kernel -C none -a 0x40008000 -e 0x40008000 -n Linux -d zImage.dtb-peach-pi uImage-peach-pi
<
Wizzup>
That doesn't seem odd right?
<
Wizzup>
(and then in u-boot: ext2load mmc 0:2 ${loadaddr} foo ; bootm ${loadaddr}
<
Wizzup>
and the loadaddr var in u-boot is OK, I think
<
javier__>
Wizzup: you are not loading your FDT
<
javier__>
Wizzup: oh, sorry is already appended
<
sjoerd>
oh appened dtb and legacy images, sadness :)
<
javier__>
Wizzup: that is correct, modulo what sjoerd said :)
<
Wizzup>
What is wrong with appended dtb? It's very simple for me when testing :)
<
sjoerd>
are you using a ye olde u-boot ooi
<
Wizzup>
sjoerd: yes! I did compile a new u-boot (mainline), but I didn't test it yet
<
javier__>
Wizzup: have to leave for today, but that branch is what I used ^^
<
Wizzup>
I wanted to use the non-mainline first, before adding two 'unsure' things
<
Wizzup>
javier__: thanks; I also have to go for a bit, but I will let you know
<
javier__>
which is just v4.0-rc6 + the exynos iommu disabled so the issue is on your setup
<
sjoerd>
Hrm, Tom didn't merge my patch to correct the default load addresses for peaches yet it seems
